Potential Health Effects
----------------------------------
Diluted solutions of sodium silicate are strong alkaline irritants. The
solid sodium silicate is corrosive. Exposure to alkaline corrosives may
result in severe burns depending on the concentration and duration of
exposure. Sodium silicate is a type of amorphous silica and does not cause
pulmonary silicosis.
Inhalation:
A strong alkaline irritant. Inhalation can cause severe irritation of
mucous membranes and upper respiratory tract. Symptoms may include burning
sensation, coughing, wheezing, laryngitis, shortness of breath, headache,
nausea and vomiting. High concentrations may cause lung damage.
Ingestion:
A strong alkaline irritant. Causes irritation to the gastrointestinal
tract. Symptoms may include nausea, vomiting and diarrhea. Solid sodium
silicate: Alkaline corrosive ingestion may produce burns to the lips,
tongue, oral mucosa, upper airway, esophagus and occasionally stomach.
Skin Contact:
A strong alkaline irritant. Causes severe irritation. Symptoms include
redness, itching and pain. Dries to form a glass film which can cut skin.
Solid sodium silicate: Dermal contact with alkaline corrosives may produce
pain, redness, severe irritation or full thickness burns.
Eye Contact:
A strong alkaline irritant. Alkaline eye exposures produce severe
irritation with effects similar to those of dilute caustics. Inflammation
or burns with possible damage to the eye tissues can occur together with
tearing and considerable pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or impaired respiratory function
may be more susceptible to the effects of the substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never
give anything by mouth to an unconscious person. Get medical attention
immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes. Remove
contaminated clothing and shoes. Get medical attention. Wash clothing
before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the
pressure demand or other positive pressure mode.
6. Accidental Release Measures
Caution! Floor and other surfaces may be slippery. Ventilate area of leak
or spill. Wear appropriate personal protective equipment as specified in
Section 8. Contain and recover liquid when possible. Collect liquid in an
appropriate container or absorb with an inert material (e. g., vermiculite,
dry sand, earth), and place in a chemical waste container. Do not use
combustible materials, such as saw dust. Do not flush to sewer!
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage. Isolate from incompatible substances.
Containers of this material may be hazardous when empty since they retain
product residues (vapors, liquid); observe all warnings and precautions
listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
Amorphous Silica, including natural diatomaceous earth:
- OSHA Permissible Exposure Limit (PEL):
(80 mg/m3) / (%SiO2) (TWA).
- ACGIH Threshold Limit Value (TLV):
10 mg/m3 (TWA) inhalable particulate;
3 mg/m3 (TWA) respirable particulate.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. Local exhaust ventilation is
generally preferred because it can control the emissions of the contaminant
at its source, preventing dispersion of it into the general work area.
Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face dust/mist respirator may be
worn for up to ten times the exposure limit or the maximum use
concentration specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. A full-face piece dust/mist respirator may
be worn up to 50 times the exposure limit, or the maximum use concentration
specified by the appropriate regulatory agency, or respirator supplier,
whichever is lowest. For emergencies or instances where the exposure
levels are not known, use a full-facepiece positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is
possible. Maintain eye wash fountain and quick-drench facilities in work
area.
